LUBRICATOR.

Application led June 3, 1913.

To all whom t may concern Be it known that I, THoMAs L. STROUD, a citizen of the United States, residing at Fort Myer, in the county of Alexandria and State of Virginia, have invented eertainnew and useful Improvements in Lubricators, of which thel following is a specification.

This invention relates to new and useful improvements in lubricators, and especially to lubricators that'can be readily attached to heavy draft vehicles. particularly wagons, gun carriages and the like. The constructionof my invention is such that it can be attached to any and all of the spindles of a wagon, and lubricate the axle thereof, without removing the'wheel therefrom.

The main object of this invention is to provide a lubricator that can be cheaply constructed, and attached to wagon axles of ordinary or usual construction without any alterations thereof.

This invention is illustrated in the accompanying drawings, which form a part of this specification and in which,

Figure 1 is a side elevation of my invention. Fig. 2 is an end view showing the end that is attached to the axle. Fig. 3 is ari end View of the opposite end of the invention. Fig. 4 isa sectional view showing my invention attached to theend of a wagon axle.

Similar characters of reference designate corresponding parts in the several figures of the drawing.

' Referring to the drawings the numeral 1 represents a cylinder having a head 2 at one end and a removable head 3 at the other end. The cylinder is designed to be iilled with a suitable lubricant for greasing axles of vehicles. The face of the head 2 is formed with a groove 4 forming a seat for a ring washer 5 and a central socket or recess 6 formed with right and left hand internal threads, for the purpose of adapting the same to be screwed onto either end of a spindle. rrrIhe head 2 is also formed with a plurality of longitudinal erforations 7 for a purpose presently set orth, and with a recess 6 surrounding the socket 6. The re cess 6a is designed to aiford space to receive the spindle shoulders in cases where the shoulders of the axle have become worn to such an extent as to permit the wheel hub to work back on the spindle and prevent a vtight joint. In such cases the head 2 may Specification of Letters Patent.

be screwed up tighter to make the joint and its recess 6 will receive the shouldered end of the spindle.

'Vlie removable head 3 of the cylinder ll is formed with oppositely disposed recesses in its periphery, which register with perforation 9 in the cylinder 1. The cylinder is reinforced around 'the opening 9 by plates 10, having a cam surface 11 for a purpose hereinafter described, said plates 10 being formed with openings 12, which register with the openings 9 and the recesses 8.

spring handle 13 in the form of aY bail, with inturned ends 14 is designed toiihold the removable head 3 in the end of the cylinder 1` the ends 14 of the handle passing through the openings 12, perforations 9, and into the recesses 8. as clearly shown in Figs. 1 and 4.

The head 3 is provided with a central internally threaded opening 15, in which a turning the rod.

In order to remove the head 3 for the purpose of supplying the cylinder with the lubricant the handle 13 is moved or turned so as to ride on the cams 11 and into the position shown in dotted lines, in Fig. 1, thereby forcing the ends 14 out of the recesses 8 of the head. The head may then be removedby drawing on the piston rod.

The handle 13 is formed with an extension 19, so that when the handle is in the position shown in broken lines in Fig'l, it may be used to assist in tightening the lubricator in place in order to compress the washer 5 and make a tight joint;

The operation of my invention is as follows: The lubricator filled with the proper device is secured in place the piston rod is e rotated, forcing the piston inward and the lubricating. material through the perfora tions in the head and around the spindle.

Having thus fully described my invention; what I claim as new, and desire to secure by Letters Patent is:

l. An axle lubricator, comprising a reservoir for the lubricant, a socketed head having longitudinally extending perforations surroundingythe socket, said socket being formed with right and left hand screwthreads, whereby the-reservoir may be secured to either endof an axle, and means operating longitudinally of said reservoir for forcing lubricant through said longitudinal perforations.

2. An axle lubricator, comprisinga reservoir for the lubricant, a socketed head having longitudinal perforations therethroug for closing one end of said reservoir, an said socket being formed with right and left hand screw-threads, a removable head closingthe other end of said reservoir, and a piston on said rod for forcing the lubricant through said perf0rations.`

3. An axle lubricator, comprising a reservoir for the lubricant, a head having a central screw threaded opening therethrough l for closing one end of said reservoir, .a threaded piston rod operating through said head and carrying al piston, a socketed head having longitudinal perforations for the other end of said reservoir, said socket being formed with yright 'and left hand screwthreads to adapt the same to either end of the axle, and a packing surrounding said socket.

4.` An axle lubricator comprising a lubricant reservoir having suitable discharge openings at its inner end and diametrically oppositeorilice near its outer end, a piston head, a head in the outer end of the reservoir having a central threaded opening, and provided with recesses in its periphery ada ted to be brought into register with the oriiizes in the reservoir, a lever handle having trunnion ends normally held seated in said orifices and recesses, and means where-` the recesses while retained `in the openings. 5. An axle lubricator comprising a lubri? cant reservoir having suitable discharge,

when turned on its ends as pivots.

6. A lubricator comprising a cylinder, a head with perforations at one end of the cylinder, a removable head at the opposite end of said cylinder; a lever handle for holding the removable head in position and mechanical means for automatically releasing the removable head when said handle is raised to a given position.

7. A' lubricator, comprising a cylinder, a i removable head forsaid cylinder, means for securing said head in position, said means comprising a bent handle havingits ends engaging said head, and means for spread-` ing the ends of said handle to release said head.

8. A lubricator lcomprising a cylinder, a

by said trunnions may be withdrawn from 'surfaces over which said lever may ride 'isv perforated head having a threaded socket for the discharge end of said cylinder, a groove formed in the end of said head, and a recess formed inthe end of said head, said vrecess being located between said groove and socket.

In testimony whereof I have aiiixed my signature yin presence of two witnesses.
